I inherited some South African recipes from cousins in Johannesburg. This is a classic. Very unusual and tasty. Edited to add: I do not purport to the recipe's authenticity, that is not for me to say, nor was it my intent on posting this recipe. I have merely had the pleasure of trying it at the home of a South African, and made it myself several times, and we much enjoy it. I suppose that there are countless variations on a theme. This is just one of them.
